Answer 2

To solve this expression, you should follow the order of operations, which is typically remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, you don't have parentheses or exponents, so you'll perform multiplication and division from left to right and then addition.

Here's how you can solve it step by step:

1. Start with the multiplication and division from left to right:

   • 5/18 + (4/45)

Now, let's perform the multiplication and division:

• 5/18 + (4/45) = (5/18) + (4/45)

Next, you need to find a common denominator for these fractions, which is 90.

• (5/18) = (5/18) * (5/5) = 25/90
• (4/45) = (4/45) * (2/2) = 8/90

So, the expression becomes:

• 25/90 + 8/90

2. Now, you can add the fractions since they have the same denominator:

• (25/90) + (8/90) = (25 + 8) / 90 = 33/90

3. Finally, simplify the fraction if possible by dividing both the numerator and denominator by their greatest common divisor, which is 3 in this case:

• (33/90) ÷ 3/3 = (11/30)

So, the final result of the expression is 11/30.
